effect, just as in H. carinata. Head rounded, not particu- 

 larly swollen behind the eyes ; cheeks beneath and anterior 

 margin of clypeus each with a large and dense brush of 

 white hairs ; anterior margins of eyes, up to a distance above 

 the level of the antenna equal to the length of the scape, 

 bordered by a conspicuous white hair-band ; vertex and the 

 rest of the face almost free from liairs, but some scattered 

 pubescence above the level of the antennse ; antennae long, 

 tlagellum brownish beneath, its first two joints about equal, 

 the third somewhat longer ; clypeus much more finely punc- 

 tured than the face above. In another specimen the clypeus 

 is covered with white hair and the face is more hairy. Thorax 

 very little hairy, the white pubescence most noticeable about 

 tubercles and along the bind margin of scutellum, but dense 

 on the ventral surface between the legs. Tegulas shining 

 piceous. Wings rather short, rather dusky, especially along 

 the costa beyond the stigma, beautifully iridescent ; nervures 

 and stigma piceous, stigma moderately well developed, first 

 recurrent nervure reaching second submarginal cell only just 

 beyond the origin of the first transverse cubital. Abdomen 

 with distinct but narrow white hair-bands, its dorsal surface 

 with very large punctures. It does not end in four projec- 

 tions, but is similar in general structure to that of H. carinata. 

 Hab. Las Cruces, N. M., on Aster spinosus, August (Ckll. 

 4626), and on Solidago canadensis, Sept. 3 (Ckll. 4748). 



h. Larger species, the red practically confined to the four 

 hindmost legs. 



Heriades higelovice^ sp. n. 



$ . Length about 5^ millim. 



More bulky than the last, the head quite large, though not 

 notably extended behind the eyes. Black, with the middle 

 and hind femora and the hind tibiaj and tarsi bright ferru- 

 ginous. Pubescence white, tolerably abundant, quite covering 

 the face up to a little below the middle ocellus, dense on the 

 cheeks beneath and along margins of mesothorax, scutellum, 

 metathorax, and pleura ; the disk of the meso- and meta- 

 thorax nude, not so the pleura ; abdominal segments with 

 very distinct apical hair-bands, snow-white, the first much 

 broadened at the side ; legs more or less white-hairy. Punc- 

 tuation of vertex, thoracic dorsum, and abdomen strong and 

 tolerably close, but not nearly so large or coarse as in the 

 carinata group. Basal enclosure of metathorax smooth, 

 shining, impunctate. Tegular testaceous, pubescent. Wings 

 perfectly hyaline, nervures and stigma piceous. Stigma
